열 유동 해석을 고려한 엔진룸 배치 최적화에 대한 연구

Recently, temperature of the engine room has been increased due to the high performance engine. Efficient and durable design of the cooling system is essential. In this paper, we considered the effect of distance between fan and heat exchangers, gap of shroud tip and the exhaust-port of substructure. Based on the results, the best cooling system of the layout for an excavator is selected. Finally, the criterion to select the best cooling system has been set up.
